msrnNsrNe TUBE on BOX.

To all whom it may concern:

Be it known that I, BENJAMIN E. D. STAF- FORD, a citizen of the UnitedStates, and a resident of Pittsburgh, in the county of Allegheny andState of Pennsylvania, have mvented certain new and useful Improvementsin Dispensing Tubes or Boxes; and I do hereby declare the following tobe a f ull, clear, and exact description of the inventlon, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in dispensing tubes or boxes andparticularly to the nozzle and closure for the same.

The object of the invention is to provide a specially designed nozzleand closure for the latter, adapted for use with collapsible tubes fordispensing paste, paint, etc-. and also for powder and other boxes, inwhich the closure is permanently secured within the nozzle and may beturned to cause a discharge opening in it to aline with a dischargeopenlng in the head of the nozzle and it consists in the features ofconstruction which will be more fully described and pointed out in theclaims.

In the accompanying drawings; Figure 1 is a view in section of a portionof the nozzle and closure; Fig. 2 is a similar view of a modification;Fig. 3 is an end view of the construction shown in Fig. 2 and Fig. 4 isa view in section partly in elevation of another modification. v

5 represents the 'head or upper end of a collapsible tube for dispensingpaste, paint, etcl, or the head of a box for dispensing powder, and 6 isthe nozzle, integral with the head. The nozzle consists of the neck anda head, the neck being cylindrical as shown and the head rounded orcurved and of greater diameter than the neck. In constructing andassembling the parts the outer end of the nozzle is open, and the spunsheet metal closure 7 is passed through the opening after which the openend of the nozzle is spun or otherwise closed down over the 010 sure asat 8, leaving a small opening at the center. The head of the nozzle thusconforms to the shape of the closure and embraces the same-snugly, theclosure-however being sufliciently loose within the head and neck sothat it may be readily turned therein. The closure 7 has a cylindricalend 8 which fits within and conforms to the neck of the Specification ofLetters Patent. Application filed. September 25, 1919.

nozzle, and the part thereof adjacent the end opening in the nozzle isslightly de-" pressed to carry it away from the wall of said opening soas to prevent the closure from binding against said wall. Secured to theclosure by riveting or otherwise is the stem 9 which passes through theend opening in the nozzle and carries at its outer endthe finger knob 10preferably milled on its periphery so that it may be readily turned.This knob closes the end opening in the nozzle and imparts an ornamentaland finished appearance to the nozzle.

he nozzle is provided with one or more side openings 11 arranged side byside as shown in Fig. 3, through which the paste or other substance isdischarged, and these openings may be flat and elongated as shown at oneside of Fig. 3 or circular as shown at the opposite side of said figure,and the closure 7 is provided with similarly shaped and placed slotsadapted to aline with the openings in the head of the nozzle for thepassage of the contents of the tube or box, or be turned out ofalinement so as to close the said slots or holes in the head.

In the construction shown in Fig. 2, the closure is expanded at theouter open end of the nozzle to approximately fill the end openingtherein, and the nozzle is slotted at for the passage of the stem l 3 ofthe finger piece 14, the said stem being riveted or otherwise secured tothe closure 7. The slot 12 in the nozzle for the sleeve of the fingerpiece is of sufiicient length to permit the closure to be moved to openand close the discharge slot or slots 11 in the nozzle.

It will of course be understood that in the construction shown in Fig. 1and also Fig. 4., means may be provided for limiting the rotary movementof the closure within the nozzle.

In the construction head of the nozzle 6 pear or ovoid in the closureknob 16 and shown in Fig. 4 the and its closure 7 are shape and theouter end of is spun outwardly to form the when the open end of thenozzle is turned down over the closure, this knob projects through thecentral opening in the head where it can be grasped by the fingers forturning the closure.

While I have shown oppositely disposed side or discharge openings ineach of the constructions illustrated, one or two 'discharge, openingsmay be used at one provided with a discharge opening side only, hence llintend that my invention shall comprehend one or more.

In all forms the closure conforms in shape to the head of the nozzle andavoids all space where the paste, paint or other contents of the tube orbox could be forced by pressure, and as the closure is confined withinthe nozzle it cannot be lost or misplaced.

It is evident that many slight changes might be resorted to in therelative arrangement of parts shown and described without departing fromthe spirit and scope of my invention. Hence ll would have it understoodthat l do not wish to confine myself to the exact construction andarrangement of parts shown and described, but

Having fully. described my invention what ll claim as new and desire tosecure by Letters-Patent, is

1. A dis ensing vessel having a nozzle a hollow closure mounted withinthe nozzle and of greater diameter than the neck of the nozzle wherebythe closure will be retained within the nozzle, the said closure havingan opening adapted to be turned into alinement with the openingin thenozzle and with a cylindrical end projecting into the neck ot thenozzle, and means secured to the closure and projecting through thenozzle whereby the resales closure may be turned to open or close thedischarge opening in the nozzle.

2. A dispensing vessel having a nozzle provided with a dischargeopening, a hollow closure mounted within the nozzle and secured thereinby upsetting the outer end of the nozzle over the outer end of theclosure,

the closure being in open communication with the vessel and providedwith an opening adapted to be turned into alinement with the opening inthe nozzle and having a centrally located knob projecting through theupset end of the nozzle.

3. A nozzle having a plurality of discharge openings located side byside, a closure mounted Within the nozzle and secured therein byupsetting the open end of the nozzle over the closure, and means securedto the closure and projecting through the nozzle whereby the closure maybe turned to open or close the discharge openings in the nozzle.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
